A gas turbine engine includes a compressor section, a combustor section and a turbine section mounted relative to an engine static structure. A module includes instrumentation that is mounted to the engine static structure. The module includes an energy harvesting power source that is configured to provide electricity to the instrumentation during engine operation and is independent of an external electrical power source.

Wireless power for gas turbine engine instrumentation

A station probe employed in a gas turbine engine includes a rake portion having a plurality of sensors for sensing conditions in the gas turbine engine. An environmental container attached to the rake portion includes signal conditioning circuitry that locally analyzes sensor signals received from the plurality of sensors to generate measured values, and a communication module for communicating the measured values to a control room.

Station probe for gas turbine engines

A turbine engine debris ingestion monitor has an acoustic emission sensor 18, 18a mounted on a surface 14, 14a disposed in an air flow stream of a turbine engine 12. The sensor converts acoustic emissions 16, generated by particles of debris 10 impacting on the surface, into an electrical signal. A counting circuit 22 (FIG. 2) processes the signal resulting in an output, indicative of the level of debris ingested into the engine, which is recorded in the aircraft's flight data recording system 110.
